Understood.
you can use the Jeti DSM-ESC, Scorpion or Optipower Backup Guard, WesternRobotics BatteryBuffer, SmartFly BattShare, a Boomarc hidden dual battery redundancy switch with pin flag, Boomarc DualBatt 2x10 isolating circuit
or a simple DIY with a common cathode diode circuit.
or as mentioned pull the red wire from the ESC BEC and get 2 small Rx batteries; one each in an available Rx port.
its whatever you feel most comfortable with.
